Method of making copper alloys.



UNITED STATES PATENT OFFICE.

GIDEON BOERICKE, OF PHILADELI'HIA, PENNSYLVANIA.

METHOD OF MAKING COPPER ALLOYS.

No Drawing.

To all whom it may concern:

Be it known that I, GIDEoN BOERICKE, a citizen of the United States, residing at Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Methods of Making Copper Alloys, of which the following is a specification.

My invention has particular reference to the production of alloys of copper with such metals as tungsten, molybdenum, vanadium, chromium and the like.

The object of my invention is the provision of a process for producing alloys of the character specified, which rocess can be economically practiced, and W ich will also produce a product of a superior character.

In carrying out my invention I prefer to use a solution of a salt of one of the metals selected, such as sodium tungstate, sodium molybdate, sodium chromate, or sodium vanadate, from which when combined with copper sulfate, a precipitate will be obtained which will be either tungstate of copper, molybdate of copper, chromate of copper, or vanadate of copper, according towh1ch material is used. .1 1

In carrying out the rocess referred to, the sulfur constituent o the cop er sulfate combines with the alkali metal in the formation in the above example of a sodium sulfate, While the tungsten, molybdenum, chromium, or vanadium is left free to combine with the cop er, forming the copper alloys referred to w ich may then be reduced to metallic form by any of the well known methods of reduction.

Specification of Letters Patent. Application filed October 31, 1908. Serial No. 460,422.

Patented May 24, 1910.

I have found in the practice of my invention in the formation, for example, of tungst-ate of copper, the product is of a very superior character, having great ductility as well as other desirable characteristics.

Having thus described my invention and illustrated its use, what I claim as new and desire to secure by Letters Patent, is the following:

1. The process of producing a copper alloy, which consists in reacting upon a salt of the metal which is to be alloyed with copper sulfate, thereby forming a precipitate, and reducing said precipitate to metallic form, substantially as described.

2. The herein described process of producing an alloy of copper, with vanadium, molybdenum, tungsten, chromium, or similar metal, which consists in the reacting upon of a solution of a salt of said metal with copper sulfate thereby forming a precipitate, and reducing said precipitate to me tallic form, substantially as described.

3. 'Ihe herein described method of forming copper alloys, which consists in reacting upon a solution of a salt of sodium tungstate, with copper sulfate, thereby forming a precipitate, and then reducing said precipitate to metallic form, substantially as described.

In testimony whereof I have hereunto signed my name in the presence of the two subscribed witnesses.

GIDEON BOERIGKE.
